Re: [Gcl-devel] Patch for configure.in

Hi Vadim,

The gcl + ilisp (under emacs or xemacs) combination hangs during
initialization, before anything can passed to gcl. Ilisp provides hooks
to execute special commands on startup, but the failure happens too

Having studied the problem more this morning I think there is something
odd in the way gcl handles its i/o that causing the problem. I am trying
to track this down now.

For now, I think the option of turning off readline support is
acceptable (it is on by default, so the usual ./configure && make
procedure is unchanged for anyone who doesn't need fix). Having the
option to turn it off may be useful for embedding gcl in other
development environments, where gcl reads from a pipe and an external
editor handles the `terminal line discipline'.

I'll still try to get around to cleaning up configure.in. I've moved our
company to autoconf-2.50 and have found it is more sensitive to proper
m4 quoting than earlier versions. Any objections?

Best Wishes,
